Determine the magnitude of the force which member CD exerts on the pin at C. A 138% Answer: CD = B 0.79 m i 0.58 m 150 N 0.58 m 38° D N 0.79 m

Determine the magnitude of force (kN) in member BC if F=73323 N, a=3.33m, b=1.14m and c=5.69m. Round off only on the final answer expressed in 3 decimal places. Instead of units, indicate C if force is compressive or Tif tensile.

do not shortcut pls. 4 decimal places

A series of compound levers is used as weighbridge. If a mass of 14.4kg is placed on the pan P and it is required that x = 475mm to balance the beam ABC, determine the mass (in 1 decimal digit of a kg) of the truck. There are pins at all points lettered. Take EF - 0. 2m, FD = 3m, KG = GH = 7m, and HI = KJ - 0.2m. 2nd question (answer in Bonus problem e): Is it necessary for the truck to be symmetrically placed on the scale? Explain. JKG & GHI are INDEPENDENT of EACH OTHER.
